WINDOW-SCREEN.

Specification of Letters Patent.

Patented Jan.. 1, 1918.

` Application led September 25, 1916. Serial No. 122,106.

dows of various heights, and a screen section which is movable in avertical direction within the same and adapted to be wound at its upperend upon a spring roller after the manner of a curtain shade.

Another object of the invention is to pro vide a screen having the abovenamed characteristics and means embodied in the frame whereby the screensection may be retained against movement in any vertically adjustedposition.

In addition to the foregoing, my invention comprehends improvements inthe details of construction, and arrangement of the correlated partswithout departing from the'.

spirit of the invention or the scope of the appended claim.

nthe accompanying drawings in which similar` and corresponding parts aredesignated by thelsam'e characters of reference throughout the severalviews in which they appear; j

Figure l, is a view in front elevation of a window s creenconstructedafter the manner of my invention, and

Figs. 2, 3 and 4, are detail sections taken on the planes indicated bynumerals corresponding t9 said figures in Fig. 1.

l/Vith reference to the drawings, 1 indi- Cates generally the verticalframe members of my improved window screen, `and 2 and 3 respectivelythe lower and upper end frame members connecting the ends of thevertical members. The upper member 3 is formed with a horizontaltransversely extended roller casing 4 formed of sheet metal or the like,having an opening 5 in its under side extending longitudinally thereof.

Each of the frame members, l as well as the frame members 2 and 3 areformed of parallel spaced sections 6 and 7, illustrated to advantage inFigs. 3 and 4, with their outer longitudinal edges liingedlyv connectedby the interengageinent of lugs 8 and 9 provided on the sections 6 and 7respectively. The frame members l, 2, and 3 thus formed are provided atsuitable intervals with transversely alined openings, ,the openings inthe member 7 being internally threaded to receive the correspondinglythreaded end of a thumb screw, the shank of which is indicated at 10,and the head 'at 11, said head bearing against the' outer surface of themember 6. Each of the frame members 1, 2, and 3, is further providedwith a series of transversely alined openings indicated at 12 for apurpose which will be presently obvious.

The ends walls 13 of the roller casing 4 provide support for thetrunnion of a roller 1l conforming to the ordinary curtain shade rollerhaving a spring therein, the trunnion being mounted within the end wallof the easing to insure operation of the roller after the manner of ashade roller. The screen section indlcated at 15 may be formed offlexible wire fabric, and in the present instance is provided upon eachlongitudinal edge with a selvage indicated at 16, and formed by bendingupon itself a strip of flexible material, which may be fabricor the likeand secured to the-wire fabric by stitching or otherwise. The lower endof the wire fabric may be also reinforced in a similar manner by abinding strip 17 The screen section is rolled upon the roller 14, andthe selvage edges thereof disposed within the space between the sectionsG and 7 of the vertical frame members 1 of the-screen frame. A handle isprovided for the screen section in the form of a loop 18 of wire or thelike secured to the binding strip 17 by means of a strip of metal 19bent upon itself bers 1 and into oneof a series of openings 21 providedfor that purposeJ in either binding strip 1l or the section 16 of thescreen section. The. screen may be *further held against displacement byturning the heads 11 of the set screws which cxtend;tl irough thevertical members of the same for binding together the sections composingthe same against the selvage edge of the screen section.

The frame of this window screen may be Varied in length by removing forinstance, the lower strip 2 from connection with the end of the framemembers l, severing said frame members 1 to a degree permitting the sameto fit within the vertical height 'of a window and -reapplying themember 2 to the severed ends` Said frame members may be secured togetherby means of the fastenings 20, which are passed through openings of theseries indicated at 12. To facilitate adjustment of the frame to anysize of window, it is preferable that the frame members be constructedof wood.

While l have illustrated and described my invention with some degree ofparticularity,

'l nevertheless realize that in practice various alterations therein maybe made, and l therefore reserve the right and privilege of changing theform of the details of conimmer In a window screen, a frame including fvertical side members and a lower horizontal connecting member, eachmember comprising a pair of strips, apertured ears on the strips, pinsentering the ears to connect the strips for relative movement, one stripof each pair having a plurality of threaded openings, and the otherstrip having registering smooth openings, to receive screws thereinwhich also enter the threaded openings, wherebyv to clamp the stripstogether. In testimony whereof I afiX my signature in presence of twowitnesses.
